1 How does artificial selection change living things over time?
Do Now: Dec 5/14 How does artificial selection change living things over time?

2 Can you think of other examples of artificial selection?
Artificial selection: The breeding of plants and animals to produce desirable traits.

5 Essential Question: How does artificial selection impact evolution?

6 Lab set up and group member roles:
Your group will need to choose a “sciency” name dealing with evolution. Choose roles for each group member Time Keeper Spokesperson Referee Note Taker Cheerleader Write down on a note card the name of your group and the roles of each member of group.

7 Fast Growing Seed Lab to simulate Selective Breeding
Today we will set up our fast growing seeds. These seed will grow in 72 hours time. When we return on Monday we will be able to complete our lab. 1. Decide what seed each table will be responsible for set up and carefully label the filter paper (use a pencil) 2. Do not add water until your group referee has checked your filter setup.

8 Do Now: Dec 8, 2014 Take out a computer and headphones
Go to cyclonescience.com and the page called “What We Did in Class Today” Follow the presentation on Evolution Today By the end of the notes you should be able to answer the following questions: What causes organisms to change over time (mechanism of evolution)? How is biotechnology and selective breeding used to change crops? Why do we use Punnett squares?

9 Do Now: 12/9/14 Take out your notes, “Evolution Today”.
Get a computer and complete the steps for “How to make a GM plant?” (10 minutes) Make sure that every group member has notes on transgenic organism and the Punnett squares for our plant lab (second STOP and JOT) Geology and Evolution Unit Test Dec 18, 2014

10 How does artificial selection impact living things over time?

11 Complete the Group Lab Sheet Remember your group roles
Lab Discussion Today Complete the Group Lab Sheet Remember your group roles Time Keeper - Make sure that each table in your group has an opportunity to share Spokesperson- Reads each question during your review Referee - Ensures every member is respected and heard Note Taker- Ensures that the group lab sheet notes are accurate and reflect the groups discussion Cheerleader- Encourages and models good listen posture (eye contact, facing the speaker)

12 Data Collection for Lab Discussion:
Take out your Punnett squares in your “Evolution Today” Note taker will make a table and record your results Plate # Seed Type and/or Crosses Outcome (What do the seeds look like?)

13 Data Analysis: What were the results?
As a group discuss the following questions: How well did your Punnett square predict the outcome of your seed crosses? Did any errors occur that could have impacted/skewed your results?

14 How can GM crops impact the way living things look over time?
Do Now Dec 10, 2014 How can GM crops impact the way living things look over time? Genetically modified crops (GMCs, GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. Definition and graph is from

15 Dr. Kuzma Social Scientist

16 How can biotechnology impact our society and environment?
Today you will “speed” review 3 new biotechnologies: GM Crops (covered during class) Genetically Modified Pets De-Extinction Biomining

17 How will we review “The Evolution Today” topics?
Topic #1 - Biomining Topic #2 - De-Extinction Topic #3 - Genetically Modified Pets Go to cyclonescience.com and the page called “What We Did in Class Today”

18 Do Now: 12/11/14 Continue the review on “Evolution Today” topics?
Topic #1 - Biomining Topic #2 - De-Extinction Topic #3 - Genetically Modified Pets Go to cyclonescience.com and the page called “What We Did in Class Today” Geology Unit Test Dec 18, 2014

19 Do Now: 12/12/14 Continue the review on “Evolution Today” topics?
Topic #1 - Biomining Topic #2 - De-Extinction Topic #3 - Genetically Modified Pets Choose a topic that your group will focus on and set up your group graphic organizer Geology Unit Test Dec 18, 2014

20 Group Graphic to Analyze the Ethical Use of New Biotechnology.
How can biotechnology impact our society and environment? What are some possible ways that we should regulate/control this new technology?

21 Materials to Support the Lesson

22 Fast Growing Plants Data 2014
Did your Punnett squares accurately predict the crosses? P1 F1 P2 F2 Data collected from our germinated seed lab.

23 Punnett Square Practice
If the blue eye allele is recessive (b) and the brown eye color is dominant (B), what would the outcome be for a parent, P1 with alleles Bb that breeds with a parent, P2 with alleles Bb. Set up a Punnett square for this cross and describe the offspring of this cross.

24 Punnett Square Practice

25 A Punnett Square is used to predict the outcome of a cross or breeding experiment.

26 Review Heredity

27 I want to hear from you: What did you think about the lesson today? What did you think about the online simulations? What could I do differently?
